Method for improving conveying efficiency of massive ore or coal

Abstract

The invention discloses a method for improving the conveying efficiency of massive ore or coal. The mined ore or coal is placed on a conveying surface at any position of a conveying belt, and the initially placed ore or coal is at least extruded on two rows of material baffles until the material baffles and the conveying surface of the conveying belt move synchronously; and then the ore or coal iscontinuously placed on the conveying surface of the bottom end part of the conveying belt to be conveyed, when the material baffles move synchronous with the conveying surface of the conveying belt,the material baffles are pulled on a conveying belt guide rail frame through a material baffle conveying belt to circularly operate, and when the material baffles move from the outer side of the conveying belt guide rail frame to the conveying belt on the inner side of the conveying belt guide rail frame, limiting columns below the material baffles slide into limiting grooves, through the joint limit of hinge points of the material baffles and the material baffle conveying belt and limit points of the limiting columns in the limiting grooves, the material baffles are unfolded on the conveyingbelt to play a material blocking role, so that the thickness of the ore or coal transported on the conveying surface of the conveying belt can be increased, and the transportation efficiency is further improved.

Description

technical field [0001] The invention relates to the technical field of transmission belt equipment used for mining in coal mines or mining plants, in particular to a method for improving the conveying efficiency of block ore or coal. Background technique [0002] In the process of coal or ore mining and transportation, the mined coal or ore is usually transported by means of V-shaped belt transportation with included angle. The reason why V-shaped belt transportation with included angle is adopted is to improve the transmission efficiency. ,like figure 1 As shown in the figure, in the process of conveying coal or ore, the conveying distance has a certain angle from the mining surface to the discharge surface, and the coal or ore conveyed is in a block structure, and the coal or ore in the block structure is in the Due to the small mutual bite force on the V-shaped conveyor belt, it is difficult to pile up too high, which leads to low transmission efficiency, and the phenome...
